5x + 7 = 3x - 5
Subtract 3x from both sides: 2x + 7 = -5
Subtract 7 from both sides: 2x = -12
Divide both sides by 2: x = -6
3x5+4=19
2+3*5 = 2 + 15 = 17

3x5 + 4x8 does not have a solution because it is not an equation. Are you looking for it's derivative? That would be: 15x4 + 32x7 Did you want it's indefinite integral? ∫(3x5 + 4x8) dx = x6/2 + 4x9/9 + C Or did you actually mean "three times five plus four times eight"? If so, the answer is 47.

(2x3)+(3x5)-(3x2)= 2x3=6 3x5=15 3x2=6 So..... 6x25-6= 6x25=150 150+6=156
3x5+4=19
2+3*5 = 2 + 15 = 17

This doesn't make any math sense:2⁴ - 1 + 21 = 14 = 7 +3 x 5
3x5 + 4x8 does not have a solution because it is not an equation. Are you looking for it's derivative? That would be: 15x4 + 32x7 Did you want it's indefinite integral? ∫(3x5 + 4x8) dx = x6/2 + 4x9/9 + C Or did you actually mean "three times five plus four times eight"? If so, the answer is 47.

No, a 3x5 matrix cannot be multiplied by another 3x5 matrix. For matrix multiplication to be possible, the number of columns in the first matrix must equal the number of rows in the second matrix. Since a 3x5 matrix has 5 columns and the second 3x5 matrix has 3 rows, multiplication is not defined in this case.

The generalisation is that multiplication is Abelian (or commutative) for numbers.
